CHAIN COUPLING.

Be it known that I, Crrannns A. Lorre- MAN, a citizen of the United States, residing at Logan in the county of State of Iowa, have invented ful Improvements in Chain which the Harrison and new and use- Couphngs, of

following is a specification.

The object of my invention is the provision of a coupling through the medium of which the ends of an automobile chain may be expeditiously and securely connected in a detachable manner so that loss of the chain is precluded and so ends of the chain may be r nected.

Other objects and practical.

that when desired the eadily disconadvantages of the invention will be fully understood from the following description. and claims when the same are read in drawing, accompanying and of this specification, in which connection with the forming part Figure 1 is a side elevation showing my novel coupling as open.

Figure 2 is a similar view showing the manner in which the coupling is closed.

Figure 3 is a longitudinal fully closed coupling.

parts in all of the views of Among other elements my novel coupling comprises a body 1 of sheet steel. or other appropriate material. The said. body 1 is generally of lJ-shape in cross-section, Figure 4-1, and is provided with a he;

cess 3 under said head.

Pivotally connected at 1 in the 1 1s a rear member 5, also id 52 and a To heel porpreferably of steel, and permanently connected at 6 to one end of a tir its forward end the member with a finger 8 as illustrated Pivotally connected at 9 in e chain 7. At 5 1s provided in Figures 1 the head portion 2 of the body 1 is a lever member 10 which is also preferably, though not necessarily, of sheet steel.

The said member 10 is designed to engage a link 11 at the opposite end of the tire chain, an

d toward said end the lever member 10 is provided in its inner edge with a recess 12 of general T- form. It will also be noticed that the lever member 10 is provided with a reduced end portion 13 and with latter being designed when the parts are shown in Figure 3.

Manifestly when the member tioned as shown by dotted lines in Figure 3, the said member 5 will permit the reduced end 13 of the lever member 10 to enter the body 1, after which the finger 8 at the inner end of the member 5 may be arranged at the outer side of the end portion 13 or" the lever member 10 as appears in full lines in Figure 3.

It will also be apparent from the foregoing that in adjusting the lever member 10 from the position shown in Figure 1 to that shown. in Figure 3 slack in the tire chain will be taken up, and when the lever mem ber 10 is in. a position shown in Figlu'e 3 pull exerted on the link 11 toward the left will tend to retain the lever member 10 in the body 1 and against the back wall of said body 1. \Vhen, however, it is desired to disconnect the link 11 it is simply necessary to swing the lever member 10, from the position shown in Figure 3 to that shown in Figure 1.

An important feature of my novel coupling resides in the capacity of the coupling to exclude from its interior ice and mud so that the coupling will be in a workable condition in all kinds of weather.

While designed more particularly for use on tire chains, my novel coupling obviously may be used in other relations where a con-- tinuous chain is employed. 7

I have specifically described. the preferred emlmdin'ient of my invention in order to impart an exact umlerstanding ot said embodiment. I do not desire, however, to be understood as confining myself to the specific disclosure inasmuch as my invention is defined by my appended claims within the scope of which changes may be made without aliecting my invention.

Having described my invention, what I claim and desire to secure by Letters-Pat ent, is zp 1. A chain coupling comprising a body of U-shape in cross-section having a head and a recess in said head, a member pivotally connected in and to the heel portion of the body and adapted to have its outer portion permanently connected to one end of a chain and having a finger on its inner portion at one of its edges, and a lever member pivot- 5 is posially connected ,in the head portion of the lever member pivoted to the head portion body and having a reduced free end porof the body and having a T-shaped recess tion arranged to rest Within and against in its inner edge and also having an end said finger, and also having a T-shaped reportion relatively arranged to assume a 5 cess in its inner edge and a lateral flange position Within and against the finger of the on its outer edge. said pivoted member when the coupling is 2. A chain coupling comprising a body in a closed state. having a head at one end and a recess in In testimony whereof I afiix my signasaid head, a member pivoted to the heel portnre.
